Fort Worth Court Grants Mandamus: Section 156.102 Applies Based on Petition Filing Date, Not Hearing Date

New Texas Court of Appeals Opinion - Analyzed for Family Law Attorneys

In re G.M., 02-26-00116-CV, April 30, 2026.

On appeal from County Court at Law of Hood County, Texas

Synopsis

Section 156.102 is triggered by the date the modification petition is filed, not the date the trial court conducts the hearing. When a party files within one year of the prior order seeking to modify the primary-residence designation, an adequate supporting affidavit is mandatory, and once the trial court finds that affidavit insufficient, it must deny the requested relief and cannot proceed to an evidentiary hearing or enter temporary orders.

Relevance to Family Law

This is a significant mandamus decision for Texas custody-modification practice. For family-law litigators handling SAPCR modifications after divorce, the opinion reinforces that the one-year gatekeeping mechanism in Family Code Section 156.102 is a filing-date rule with teeth: if the petition is filed within one year of the prior order and seeks to change the conservator with the exclusive right to designate the child’s primary residence, the movant must satisfy the affidavit requirement at the outset or the case cannot proceed on that request. Strategically, this affects emergency filing decisions, pleading practice, temporary-orders strategy, and preservation when opposing counsel attempts to push a deficient early-filed modification into a live hearing anyway.

Case Summary

Fact Summary

The parties’ divorce decree gave Mother the exclusive right to designate the child’s primary residence and to enroll the child in school, while the parties exercised alternating weeks of possession. In later modification proceedings initiated by Mother, the trial court orally rendered judgment on October 30, 2024, leaving only a Christmas-possession detail unresolved at that hearing, and later signed a written order on January 2, 2025. Under that modified order, Mother retained the exclusive right to designate the child’s primary residence and school.

In October 2025, Mother moved approximately an hour away and enrolled the child in school in the new city. That move materially affected the logistics of Father’s possession periods because, during Father’s weeks, the child would face substantial commuting time and Father would bear extensive daily driving obligations.

Father responded by filing a petition to modify on October 24, 2025, seeking to be named the conservator with the exclusive right to determine the child’s primary residence. Because that request sought to modify the primary-residence designation within one year of the prior order, Section 156.102 was implicated if the filing date controlled.

At the subsequent hearing on November 7, 2025, the trial court found Father’s supporting affidavit insufficient. Mother argued that, under Section 156.102(c), the court was required to deny the requested relief and refuse to proceed. The trial court nevertheless moved forward, apparently reasoning that more than one year had elapsed between the prior rendition date and the hearing date, making the affidavit defect irrelevant. After taking evidence, the court entered temporary orders, including transportation provisions, a reduction in child support, and the appointment of an amicus attorney.

Mother sought mandamus relief.

Issues Decided

The Fort Worth Court of Appeals decided the following issues:

Rules Applied

The court’s analysis centered on Texas Family Code Section 156.102.

The court also relied on plain-language statutory-construction principles, including the Texas Supreme Court’s directive in Baumgardner v. Brazos River Authority, 714 S.W.3d 597, 601 (Tex. 2025), that courts apply the plain meaning of statutory text and give effect to every word.

In addressing competing authority, the court contrasted:

The court also referenced In re J.A., No. 02-21-00140-CV, 2022 WL 2353096 (Tex. App.—Fort Worth June 30, 2022, no pet.) (mem. op.), for the proposition that Section 156.102’s heightened pleading requirement does not apply to an amended modification pleading filed more than one year after the order to be modified.

Application

The court treated the dispute as a straightforward statutory-text problem. Section 156.102(a) applies if the suit is “filed” within one year of rendition of the prior order. Father filed on October 24, 2025. Whether the relevant prior date was the October 30, 2024 oral rendition or the January 2, 2025 signed order, the petition was filed within one year. That meant the statute applied.

The trial court effectively substituted the hearing date—November 7, 2025—for the filing date in determining whether the statute was triggered. The appellate court rejected that approach because the statutory text does not make the hearing date relevant to applicability. The operative event is the filing of the modification suit. The court acknowledged that older authority could be read to give significance to hearing timing, but it concluded that plain-text analysis and more recent authority compelled the opposite result.

Once the court established that Section 156.102 applied, the rest followed from subsection (c). The trial court had already found Father’s affidavit insufficient. At that point, the statute did not leave room for discretion. The court was required to deny the requested relief and refuse to proceed with a hearing on that modification request. Instead, it conducted the hearing, heard evidence, and entered temporary orders. That sequence was the abuse of discretion mandamus was designed to correct.

The opinion is especially important because it rejects the practical-but-incorrect idea that an affidavit defect becomes harmless once the court goes ahead and hears evidence anyway. The statute is a pre-hearing screening device. If the statutory threshold is not met, the court cannot cure the defect by simply moving forward.

Holding

The court held that Section 156.102 is triggered by the date the petition to modify is filed, not by the date of the hearing. Because Father filed his petition within one year of the prior order, his request to change the person holding the exclusive right to designate the child’s primary residence was subject to the statute’s affidavit requirement.

The court further held that, after finding Father’s supporting affidavit insufficient, the trial court had a mandatory duty under Section 156.102(c) to deny the requested relief and refuse to proceed with a hearing. By going forward with the hearing and entering temporary orders anyway, the trial court abused its discretion.

Accordingly, the Fort Worth Court of Appeals conditionally granted mandamus relief.

Practical Application

For practitioners, the case clarifies several recurring modification scenarios. First, if you are filing to change the primary-residence designation within one year of the prior order, your first strategic question is not whether you can get the hearing set after the anniversary date; it is whether your petition is being filed before that anniversary date. If yes, Section 156.102 applies, and the affidavit must stand on its own statutory sufficiency.

Second, this opinion is a reminder that trial courts do not have procedural discretion to “just hear it” once they conclude the affidavit is deficient. If you represent the respondent, press for a ruling on the affidavit before evidence begins, object to any further proceedings after an insufficiency finding, and make a clean record that Section 156.102(c) requires denial of the requested relief. This is a preservation case as much as it is a pleading case.

Third, in emergency or fast-moving relocation disputes, counsel should separate what relief is actually being sought. If the movant wants to change the primary-residence designation within one year, Section 156.102 will likely control. If the real concern is transportation, school logistics, exchange details, or other temporary management issues, pleadings should be evaluated carefully to determine whether the requested relief can be framed without triggering the one-year affidavit gatekeeper. The opinion does not invite artful pleading, but it does underscore the importance of precision in defining the modification sought.

Fourth, for the movant, an insufficient affidavit is not a technicality. It can halt the case before a hearing occurs. Lawyers should draft affidavits as evidentiary roadmaps that expressly track the statutory grounds and present concrete facts, not conclusions. A conclusory affidavit may now be more likely to generate mandamus-worthy error if a trial court proceeds despite the defect.

Finally, this case has broader relevance to post-divorce custody litigation because early modifications often arise when a parent relocates, remarries, changes schools, or encounters a new possession-related burden shortly after entry of an order. Those are exactly the kinds of cases where litigants may feel pressure to file quickly. In re G.M. confirms that filing quickly has procedural consequences, and those consequences cannot be avoided by waiting to hold the hearing until after the one-year mark has passed.
